We construct a vintage capital à la Whelan (2002) with both exogenous embodied and disembodied technical progress, and variable utilization of each vintage. The lifetime of capital goods is endogenous and it relies on the associated operation costs. Within this model, we identify the rate of...

This paper studies the conditions under which new equipment may endogenously occur. To this end, we construct an endogenous growth multisectoral model with a preeminent new equipment sector. Technological progress is embodied: New machines can only be run on the most recent generations of...

This paper studies the conditions under which an IT revolution may occur and have permanent effects on long-term growth. To this end, we construct a multi-sectoral growth model with endogenous embodied technical progress. The R&D sector expands the range of softwares. The capital sector produces...

This paper analyzes the equilibrium dynamics of an AK-type endogenous growth model with vingage capital. The inclusion of vintage capital leads to oscillatory dynamics governed by replacement echoes, which additionally influence the intercept of the balanced growth path. These features, which...

We study an optimal growth model with one-hoss-shay vintage capital, where labor resources can be allocated freely either to production, technology adoption or capital maintenance. Technological progress is partly embodied. Adoption labor increases the level of embodied technical progress....
